DETAILED DESCRIPTION

Reference will now be made in detail to the present embodiments of the disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
Refer to FIG. 1 and FIG. 2. FIG. 1 is an exploded drawing of a solar power module 1 according to an embodiment of the disclosure. FIG. 2 is an assembly drawing of the solar power module 1 in FIG. 1.
As shown in FIG. 1 and FIG. 2, the solar power module 1 includes a first frame 10, a second frame 12, and a solar cell laminate member 14. In particular, the first frame 10 and the second frame 12 have the same shape and can be stacked one another. The solar cell laminate member 14 is clamped between the first frame 10 and the second frame 12, so as to form the solar power module 1.
The solar cell laminate member 14 of the solar power module 1 can be manufactured by a lamination process (the material can be glass), and the solar cell laminate member 14 includes a plurality of solar cell units 140 laminated therein. The solar cell units 140 of the solar cell laminate member 14 are electrically connected to each other (in series or in parallel) and can absorb sunlight to generate electric current, so as to achieve the purpose of generating electricity. The detailed structures of the first frame 10 and the second frame 12 are described below.
Refer to FIG. 3. FIG. 3 is a partial cross-sectional view of the solar power module 1 in FIG. 2 along line 3-3′.
As shown in FIG. 1 and FIG. 3, the first frame 10 of the solar power module 1 includes a first main body 100 and a first clamping portion 102. The first main body 100 of the first frame 10 is rectangular ring-shaped. The first clamping portion 102 of the first frame 10 is disposed along an inner edge 100 a of the first main body 100 to be ring-shaped. The second frame 12 of the solar power module 1 includes a second main body 120 and a second clamping portion 122. The second main body 120 of the second frame 12 is rectangular ring-shaped and abuts on the upper surface of the first main body 100. The second clamping portion 122 of the second frame 12 is disposed along an inner edge 120 a of the second main body 120 to be ring-shaped and corresponding to the first clamping portion 102 of the first frame 10.
The contour of the periphery of the solar cell laminate member 14 of the solar power module 1 is similar to the contour of the first main body 100 of the first frame 10 and the contour of the second main body 120 of the second frame 12. When the first frame 10 and the second frame 12 of the solar power module 1 are stacked one another to make the second main body 120 abut on the first main body 100, the solar cell laminate member 14 is surrounded within the inner edge 100 a of the first main body 100 and the inner edge 120 a of the second main body 120, so as to achieve the purpose of retaining the solar cell laminate member 14.
Moreover, the periphery of the solar cell laminate member 14 of the solar power module 1 is clamped between the first clamping portion 102 and the second clamping portion 122. In the embodiment of the disclosure, the solar cell units 140 in the solar cell laminate member 14 are not overlapped with the first clamping portion 102 of the first frame 10 and the second clamping portion 122 of the second frame 12, so that the overall power efficiency of the solar power module 1 is not affected by the first clamping portion 102 and the second clamping portion 122.
In the embodiment of the disclosure, the solar power module further includes glue 2. The glue 2 is adapted for adhering the first clamping portion 102 of the first frame 10, the second clamping portion 122 of the second frame 12, and at least a part of the periphery of the solar cell laminate member 14. By using the glue 2 to fixing the solar cell laminate member 14 between the first frame 10 and the second frame 12, the solar power module 1 not only can rapidly fix the solar cell laminate member 14 but also can save the costs of installation.
Refer to FIG. 4. FIG. 4 is a partial cross-sectional view of the solar power module 1 in FIG. 3 along line 4-4′.
As shown in FIG. 3 and FIG. 4, the first clamping portion 102 of the first frame 10 has two opposite first grooves 102 a respectively located at the upper surface and the lower surface of the first clamping portion 102 adjacent to the inner edge 100 a of the first main body 100. The second clamping portion 122 of the second frame 12 has two opposite second grooves 122 a respectively located at the upper surface and the lower surface of the second clamping portion 122 adjacent to the inner edge 120 a of the second main body 120. The first groove 102 a on the upper surface of the first clamping portion 102 faces to the second groove 122 a on the lower surface of the second clamping portion 122. When the first frame 10 and the second frame 12 of the solar power module 1 are stacked one another to make the second main body 120 abut on the first main body 100, the first groove 102 a of the first clamping portion 102 and the second groove 122 a of the second clamping portion 122 form an overflow groove 110. When the glue 2 is adhered to the solar cell laminate member 14 between the first clamping portion 102 of the first frame 10 and the second clamping portion 122 of the second frame 12, a part of the glue 2 flows to be accommodated in the overflow groove 110.
Furthermore, the first grooves 102 a are adjacent to the junction of the first clamping portion 102 and the first main body 100, and the second grooves 122 a are adjacent to the junction of the second clamping portion 122 and the second main body 120, but the disclosure is not limited in this regard.
In the embodiment of the disclosure, the first groove 102 a is formed on the first clamping portion 102 along the inner edge 100 a of the first main body 100, and the second groove 122 a is formed on the second clamping portion 122 along the inner edge 120 a of the second main body 120, so as to make the overflow groove 110 be ring-shaped. Accordingly, the whole periphery of the solar cell laminate member 14 is clamped between the first clamping portion 102 and the second clamping portion 122 and is accommodated in the overflow groove 110. However, the shape of the first groove 102 a of the first clamping portion 102, the shape of the second groove 122 a of the second clamping portion 122, and the shape of the overflow groove 110 are not limited by the embodiment.
Refer to FIG. 5. FIG. 5 is a partial cross-sectional view according to another embodiment of the disclosure, in which the location of the section is similar to that in FIG. 4.
As shown in FIG. 3 and FIG. 5, both the upper surface and the lower surface of the first clamping portion 302 have plurality of first grooves 302 a, and both the upper surface and the lower surface of the second clamping portion 322 have plurality of second grooves 322 a. Each of the first grooves 302 a on the upper surface of the first clamping portion 302 faces to and is aligned with the corresponding one of the second groove 322 a on the lower surface of the second clamping portion 322. Accordingly, the first grooves 302 a on the upper surface of the first clamping portion 302 and the second grooves 322 a on the lower surface of the second clamping portion 322 form a plurality of overflow grooves 310. When the glue 2 is adhered to the solar cell laminate member 14 between the first clamping portion 302 and the second clamping portion 322, parts of the glue 2 flows and is accommodated in the overflow grooves 310.
Furthermore, the sections of the first grooves 302 a are separately formed on the first clamping portion 302 and line along the junction of the first clamping portion 302 and the first main body 100. The sections of the second grooves 322 a are separately formed on the second clamping portion 322 and line along the junction of the second clamping portion 322 and the second main body 120. Accordingly, when the solar cell laminate member 14 is clamped between the first clamping portion 302 and the second clamping portion 322, parts of the periphery of the solar cell laminate member 14 are located in the overflow grooves 310.
Compared with the embodiment in the FIG. 4, the sections of the first grooves 302 a on the first clamping portion 302 and the sections of the second grooves 322 a on the second clamping portion 322 of the embodiment separately form plural recesses, rather than an integral ring-shaped recessed structure. Therefore, the first clamping portion 302 and the second clamping portion 322 of the embodiment have better structural strengths.
Compared with the embodiment in the FIG. 4, the total space capacity of the separate overflow grooves 310 is smaller. Therefore, less amount of glue 2 to adhere the solar cell laminate member 14 is needed in this embodiment.
As shown in FIG. 3, the first frame 10 of the solar power module 1 further includes a first stand portion 104. The first stand portion 104 of the first frame 10 is disposed at the outer edge 100 b of the first main body 100. An angle θ is included between the first stand portion 104 and the first main body 100, which is preferably an obtuse angle, for example in a range of about 100 to about 150 degrees. The second frame 12 of the solar power module 1 further includes a second stand portion 124. The second stand portion 124 of the second frame 12 is disposed at the outer edge 120 b of the second main body 120 and corresponding to the first stand portion 104. Similarly, an angle θ is included between the second stand portion 124 and the second main body 120, which is preferably an obtuse angle, for example in a range of about 100 to about 150 degrees.
In particular, as shown in FIG. 1, the first stand portion 104 of the first frame 10 extends outwardly and downwardly from the outer edge 100 b of the first main body 100. The first stand portion 104 includes a plurality of sub-stands, for example, a first sub-stand 1041, a second sub-stand 1042, and two third sub-stands 1043. The first sub-stand 1041 and the second sub-stand 1042 are respectively connected to the two opposite outer edges of the first main body 100 and the third sub-stands 1043 are respectively connected between the first sub-stand 1041 and the second sub-stand 1042. Similarly, the second stand portion 124 of the second frame 12 extends outwardly and downwardly from the outer edge 120 b of the second main body 120. The second stand portion 124 includes a plurality of sub-stands, for example, a fourth sub-stand 1241, a fifth sub-stand 1242, and two sixth sub-stands 1243. The fourth sub-stand 1241 and the fifth sub-stand 1242 are respectively connected to the two opposite outer edges of the second main body 120 and the sixth sub-stands 1243 are respectively connected between the fourth sub-stand 1241 and the fifth sub-stand 1242. Accordingly, when the first frame 10 and the second frame 12 of the solar power module 1 are stacked one another to make the second main body 120 abut on the first main body 100 (as shown in FIG. 2 and FIG. 3), the first stand portion 104 of the first frame 10 and the second stand portion 124 of the second frame 12 do not interfere with each other. On the contrary, the first frame 10 is located in the accommodating space S of the second frame 12, and the first stand portion 104 of the first frame 10 and the second stand portion 124 of the second frame 12 are stacked and abutted against each other.
In an embodiment of the disclosure, the first frame 10 and the second frame 12 are stacked and placed on a horizontal plane. When the gravity force direction is defined to be 0 degree, an inclined angle by which the first stand portion 104 of the first frame 10 is inclined relative to the outer edge 100 b of the first main body 100, and the inclined angle by which the second stand portion 124 of the second frame 12 is inclined relative to the outer edge 120 b of the second main body 120 are both within the range of 10˜60 degrees. However, the disclosure is not limited in this regard.
As shown in FIG. 1, a length of the first sub-stand 1041 of the first stand portion 104 at the front side of the first frame 10 is different from a length of the second sub-stand 1042 of the first stand portion 104 at the rear side of the first frame 10, for example, the length of the first sub-stand 1041 is smaller than the length of the second sub-stand 1042. A length of the fourth sub-stand 1241 of the second stand portion 124 at the front side of the second frame 12 is different from a length of the fifth sub-stand 1242 of the second stand portion 124 at the rear side of the second frame 12, for example, the length of the fourth sub-stand 1241 is smaller than the length of the fifth sub-stand 1242. Hence, the inclined design of the solar power module 1 of the embodiment that makes the solar cell laminate member 14 be inclined relative to the ground has the advantage of effectively utilizing sunlight.
Refer to FIG. 6 and FIG. 7. FIG. 6 is a top view of the solar power module 1 in FIG. 2. FIG. 7 is a partial cross-sectional view of the solar power module 1 in FIG. 6 along line 7-7′.

The fourth sub-stand 1241 and the fifth sub-stand 1242 of the second stand portion 124 of the second frame 12 each has a plurality of second screw bosses 124 a. The first screw bosses 104 a of the second sub-stand 1042 of the first stand portion 104 are disposed at the inner side of the first stand portion 104, and the second screw bosses 124 a of the fifth sub-stand 1242 of the second stand portion 124 are disposed at the inner side of the second stand portion 124. When the first frame 10 and the second frame 12 of the solar power module 1 are stacked and the second main body 120 abuts against the first main body 100, the first screw bosses 104 a connect and align with the second screw bosses 124 a, as shown in FIG. 7.
Furthermore, the solar power module 1 further includes screws 16. Each of the screws 16 is fastened to the first screw boss 104 a and the corresponding second screw boss 124 a, so as to increase the fixing strength between the first frame 10 and the second frame 12.
As shown in FIG. 7, each of the first sub-stand 1041 and the second sub-stand 1042 of the first stand portion 104 of the first frame 10 further has a plurality of first outlet holes 104 b. The first outlet holes 104 b of the first stand portion 104 are adjacent to and connect the first screw bosses 104 a, respectively. Each of the fourth sub-stand 1241 and the fifth sub-stand 1242 of the second stand portion 124 of the second frame 12 further has a plurality of second outlet holes 124 b. The second outlet holes 124 b of the second stand portion 124 are adjacent to and connect the second screw bosses 124 a, respectively.
Furthermore, the first outlet holes 104 b through the first stand portion 104 are formed along the fastening direction (i.e., the vertical direction in FIG. 7), and the first screw bosses 104 a and the first outlet holes 104 b are overlapped in the top view, respectively. Similarly, the second outlet holes 124 b through the second stand portion 124 are formed along the fastening direction, and the second screw bosses 124 a and the second outlet holes 124 b are overlapped in the top view, respectively.
Accordingly, each of the screws 16 of the solar power module 1 can sequentially passes through the corresponding second outlet hole 124 b of the second stand portion 124 and the corresponding first outlet hole 104 b of the first stand portion 104, and then be sequentially fastened to the corresponding second screw boss 124 a of the second stand portion 124 and the corresponding first screw boss 104 a of the first stand portion 104 along the fastening direction.
Refer to FIG. 8. FIG. 8 is a rear view of the solar power module 1 in FIG. 1.
As shown in FIG. 8, the first stand portion 104 of the first frame 10 has two first outlet holes 104 b located at the rear side of the first stand portion 104, the second stand portion 124 of the second frame 12 has two second outlet holes 124 b located at the rear side of the second stand portion 124, and each of the first outlet holes 104 b is communicated with the corresponding second outlet hole 124 b.
The solar power module 1 further includes a junction box 18. The junction box 18 of the solar power module 1 is disposed at the interior of the first frame 10 and the second frame 12 and includes a positive electrode cable 180 and a negative electrode cable 182. The cable 180 for connecting positive electrode of the junction box 18 passes through one of the first outlet holes 104 b and the corresponding second outlet hole 124 b (i.e., the left first outlet hole 104 b and the left second outlet hole 124 b in FIG. 8). The cable 182 for negative electrode of the junction box 18 passes through another of first outlet holes 104 b and the corresponding second outlet hole 124 b (i.e., the right first outlet hole 104 b and the right second outlet hole 124 b in FIG. 8).
In general, an outdoor solar power system includes a plurality of the solar power modules 1 that are disposed side by side and electrically connected to each other. The solar power system further includes a plurality of connectors 19. As shown in FIG. 8, the connector 19 on the left side links the cable 180 for connecting positive electrode of the junction box 18 and the cable 182 for connecting negative electrode of another junction box (not shown) on another left solar power module (not shown). The connector 19 on the right side links the cable 182 for connecting negative electrode of the junction box 18 and the cable 180 for connecting positive electrode of another junction box (not shown) on another right solar power module (not shown). Therefore, the solar power modules 1 included in the solar power system can be electrically connected to each other under this construction.
Refer to FIG. 9 and FIG. 10. FIG. 9 is a top view of a solar power system according to another embodiment of the disclosure. FIG. 10 is a partial cross-sectional view of the solar power system in FIG. 9 along line 10-10′.
As shown in FIG. 9 and FIG. 10, the solar power system includes two brackets 526. The brackets 526 of the solar power system are disposed under the first frame 10 of the solar power module 1 and abut against the first stand portion 104 (as shown in FIG. 10). Each of the brackets 526 has a plurality of screw holes 526 a, and each of the screw holes 526 a is located right under the corresponding second screw boss 124 a of the second stand portion 124 and the corresponding first screw boss 104 a of the first stand portion 104. Therefore, after respectively passing through the first screw bosses 104 a and the second screw bosses 124 a, the screws 56 can be further respectively fastened to the screw holes 526 a of the brackets 526, so as to fix the first frame 10 and the second frame 12 on the brackets 526. By fastening the solar power modules 1 to the brackets 526, the overall structural strength of the solar power system can be improved. Even in the severe external environment (e.g., natural disasters such as typhoons), the solar power modules 1 included in the solar power system can still be on the brackets 526 stably.
As shown in FIG. 1, the first stand portion 104 of the first frame 10 is disposed along the outer edge 100 b of the first main body 100 to be ring-shaped, and the second stand portion 124 of the second frame 12 is disposed along the outer edge 120 b of the second main body 120 to be ring-shaped. Therefore, the solar power module 1 has enough supporting force at the bottom to bear a weight of the solar power module 1, but the disclosure is not limited in this regard.
Refer to FIG. 11. FIG. 11 is an exploded drawing of a solar power module 7 according to another embodiment of the disclosure.
As shown in FIG. 11, this embodiment is under the condition that the new structure does not decrease the overall strength of the solar power module 7. The first main body 700 and the first clamping portion 702 of the first frame 70 are respectively similar to that of the first frame 10 in FIG. 1, but the first stand portion 704 of the first frame 70 is discontinuously disposed at the partial outer edge of the first main body 700 (e.g., the front edge and the rear edge of the first main body 700). For example, the first stand portion 704 merely includes a first sub-stand 7041 and a second sub-stand 7042, a length of the first sub-stand 7041 is smaller than a length of the second sub-stand 7042. The first main body 700 and the first sub-stand 7041 include an included angle θ₁therebetween while the first main body 700 and the second sub-stand 7042 include an included angle θ₂therebetween, in which θ₁>θ₂. Similarly, the second main body 720 and the second clamping portion 722 of the second frame 72 are respectively similar to that of the second frame 12 in FIG. 1, but the second stand portion 724 of the second frame 72 is discontinuously disposed at the partial outer edge of the second main body 720 (e.g., the front edge and the rear edge of the second main body 720). For example, the second stand portion 724 merely includes a third sub-stand 7241 and a fourth sub-stand 7242, a length of the third sub-stand 7241 is smaller than a length of the fourth sub-stand 7242. The second main body 720 and the third sub-stand 7241 include an included angle θ₃therebetween while the second main body 720 and the fourth sub-stand 7242 include an included angle θ₄therebetween, in which θ₃>θ₄. Hence, the costs of material for the solar power module 7 can be saved.
